A common image associated with climate change is the lone polar bear stranded on a melting glacier in the middle of a large body of water; yet Courtney Mattison wants to draw people's attention to another devastating consequence of such an environmental threat. Courtney Mattison has created a stunning coral reef sculpture by hand to signify how much they have changed over the years.

Titled Our Changing Seas III, Courtney Mattison's sculpture is rich and vibrant in the center, becoming more white as it moves outwards. This represents the bleaching transition the coral reefs are going through. Courtney Mattison points out, "There is still time for corals to recover even from the point of bleaching if we act quickly to decrease the threats we impose."
